Striate palmoplantar keratoderma: a clinical and ultrastructural study.
Palmoplantar keratodermas are poorly understood heterogeneous disorders of cornification. Autosomal dominant and autosomal recessive keratodermas with a varied clinical presentation are recognized. Striate keratoderma is uncommon. We report the case of a 15-year-old girl with keratoderma that began at 5 months of age. Her clinical and ultrastructural findings are reviewed. Routine microscopic examination revealed eosinophilic inclusions in the granular cell layer as well as prominence of the granular cell layer. Electron microscopic examination revealed corneocytes with an imbricated pattern. Ultrastructural findings in this unique case are contrasted with those of other palmoplantar keratodermas.
